I found something odd using pyste : From the header myHeader.h | class A | { | public: | void f(); | void f(const int* const arg); | }; and the corresponding interface file | Class("A", "myHeader.h") Pyste generates the following wrapper code | void Export_myHeader() | { | boost::python::class_< A >("A", boost::python::init< >()) | .def(boost::python::init< const A& >()) | .def("f", (void (A::*)() )&A::f) | .def("f", (void (A::*)(const int*) )&A::f) | ; | } This problem is that A::f(const int* const) can not be casted into void(A::*)(const int*) (the second const is missing). This problem seems to come from Pyste itself as the xml description generated by gccxml is correct (leads to a const pointer on a const int). _john.
